First bit of advice, order the ABS hubs, there are only 2 differences, a wiring connector, and the price. For some reason the ABS ones are cheaper, just clip the wire off and they work the same. I always use timken, but I haven't actually tried the cheaper ones just for fear they wouldn't last. I did install a set of GMB hubs on a 2002, but that was too recently to tell how they are holding up.

I did something cheap from Advance Auto and they didn't last, more recently I went with Moog/National and paid a whole lot more. Can't yet say if they will last longer but I can say avoid the budget stuff.

I look at it this way. On my olds van it uses the same bearing on the front as the impala.
Four years ago the front right bearing got noisy so i questioned how long i was going to keep the van so i looked at the cost , build quality, specks warranty and price. So i picked the option of the store brand and put it on.
Last year i was inspecting the van and found the driver side was starting give a bit of play so back to the parts store and put the same on as i did before #513179. Today i have had no trouble at all with the so called cheep bearings. Parts guys like the up sell.
The warranty is one year just like gm.
The van is run as a daily driver and a fair bit of highway trips as well. So with the bearing instaled and torqued to the proper specks i will say that there as good as the factory instaled bearings.
On a side note i put on a front bearing on my daughters car this spring due to the factory one failed Integral ABS. No problems

Factory bearing lasted like 7 years on my wife's car, the Advance Auto cheapies were noisy in under a year and a half BOTH. Hell they might have been shot inside the 1 year warranty but I avoid riding in the wife's car and the wife is as good at reporting automotive issues as sterotypes suggest she should be. Hell it is not uncommon for me to need to drive her car and find a CEL, low fuel light and low tire in one trip.

I want to say the first ones I used were REAL cheap like $45 maybe you got something midlevel pricewise that is a lot better than the crap I bought first.

hmm yeah i wondered that about the ABS vs. non-ABS versions. I'll get the ABS version for sure.
So any tips you all can give me on the procedure? like what size socket for the axle nut. Do I have to push the axle out of the hub? Does that mean I have to disconnect the control arm ball joint and the tie rod end?

Here are the non-ABS Timken part numbers, should they by chance be a better bargain.
TIMKEN Part # HA590085 {#513160, HA590048}

The ones with ABS:
TIMKEN Part # 513179 {#HA590093}

The ones in braces are earlier / alternate part numbers.

You will need to push the axles out. That may require a puller. Also, you're supposed to replace the axle nut when you do this. It needs a 34 or 35mm socket - can't recall which.

Similarly, you're supposed to use new bolts on the hubs. BEWARE: The replacement bolts I got from the dealer had 1/2" heads. The originals were 13mm. I rounded one some before I realized they were different. I know it's a tiny diff, but the bolts are in a bit of an awkward position wherein it's hard to keep the socket all the way seated and perfectly on axis, so the conditions are right for rounding.

I disconnected the steering knuckle from the strut, and left the ball joint connected. Can't recall if I did anything with the tie rod end.

You might get lucky and the axel shaft may be able to move with a bit of help from a big hammer to tap the shaft back into the wheel bearing verses the puller. anti seize and locktite (red) and a torque wrench also.

The hub nut is 34mm, just pull the caliper bracket off, rotor, disconnect the tie-rod end, and pull the two bolts mounting the knuckle to the strut. Beat the end of the axle back with a big hammer, and you'll be able to get the bolts out for the hub. I use a wobbler attachment on the socket for easier access.
